Given numbers are 858, 658, 531, 782
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(858, 658) = 282282
GCD(858, 658) = ( 858 x 658 ) / 282282
= 858 / 658
= 858
Step2:
LCM(2, 531) = 1062
GCD(2, 531) = ( 2 x 531 ) / 1062
= 2 / 531
= 2
Step3:
LCM(1, 782) = 782
GCD(1, 782) = ( 1 x 782 ) / 782
= 1 / 782
= 1
So, Greatest Common Divisor of 858, 658, 531, 782 is 1
